J'ACOIBUS TEN DOORNKAAT-KOOLMAN, OF CASSEL, GERMANY.

Specification of Letters Patent.

Patented July 12, 1910.

Application filed January 24, 1907. Serial No. 353,874.

To all whom 'it may concern:

Be it known that I, J ACOBUS TEN DooRN- KAAT-KOOLMAN, a citizen of theGerman Empire, and resident of Cassel, Germany, have invented certainnew and useful Improvements in Devices for Cooling Store- Vats andSimilar Receptacles, of which the following is a specification.

In cooling-chambers, and particularly in those of breweries, in whichthe so-called store-vats are put up, the cooling is, as a rule, effectedby a system of cooling-pipes passing through the room, arranged on theceiling, and constantly kept in operation. This cooling system has,however, the drawback that, if the vats are to be kept cool, the wholeroom requires to be filled with the cooling-medium and that, moreover,the upper part of the store-vats is not sufficiently cooled, as theco0ling-mediumcooled airin consequence of the greater specific weightcollects on the whole at the bottom.

The present invention removes this-drawback by giving to the store-vatssuch a form that there remains a cuneiform interspace between the same,which forms a cooling space and transmits the cooling action immediatelyto the store-vats. In this way the store-vats are cooled in the mostnatural manner, as the cold air is first conveyed to the upper part ofthe vats and the cold is transmitted by the liquid to the lower strataof the same, that is to say the contents of the vat are cooled in themain from the inside.

The drawing shows a sample form of the construction of the invention.

Figure 1 is a cross-section on the line AB of Fig. 3, Fig. 2 alongitudinal section.

on the line C D of'Fig. 3, and Fig. 3 a horizontal sectionon the line EF of Fig. 1.

Similar letters refer to similar parts throughout the several views.

The vats or vessels a, which may be of cement, wood, metal or any othersubstances, are preferably of a stack-shaped cross-section, while in thelongitudinal direction they may be of the form of an ordinary cask, thatis to say be bulged out or straight. The cuneiform space I)remaining-between any two vats, is closed at both ends, so that areservoir is formed in this way. The inside wall of this reservoir mayeventually be coated with an impervious layer The reservoir thusproduced may also be divided into-two parts by a partition-wall cl. Itwill be seen that the walls of each vat extend above the roof thereof,thereby forming the refrigerant reservoir 6. a i

In order to facilitate access to the interior of each vat for thepurposes of cleaning and repairing the same, the portion of the frontwall, a, is so formed adjacent to its center as to leave a part of theroof without the refrig erant reservoir, as at (23', this part of theroof being provided with a manhole 7.: having a removable cover is.

Through the spaces b there are led cooling-pipes f, g, which communicatewith an ice machine. To these cooling-pipes are connectedserpentine-pipes e in the spaces b. The remaining space or spaces 6 arefilled with water or brine, and the Whole closed at the top by suitableplates h. If through the system of'pipes e, f, 9, there is conducted acooling medium and the liquid in the space Z) is caused to freeze, then,as the cold chiefly passes toward the bottom, it must take its directiontoward the interior of the vats, especially if the two ends of thereservoir 1) are closed with a material which is a bad conductor ofheat. occurs that the fluid frozen in 6 begins to thaw again, all thatis required then is to let a cooling medium pass again through thesystem of pipes. In this way there is effected an intense immediatecooling of the vats and from above, while the loss in cooling medium isreduced to a minimum. By this cooling process the vats are constantlysurrounded by ice in the cuneiform interspaces which need only be thawedif repairs are required.
